I'm studying published journal articles on my topic, and I'd like to reproduce their analysis. How can I get a copy of their dataset and enough specifications to reproduce their numerical results?
In my specific case, I'm studying this work: Stecklov et al. (2005), published in Demography, and they're using PROGRESA datasets which are publicly available, but when I try to reproduce their results, all the base statistics are off by a bit, and the regressions come out a bit different. Probably I'm just including or excluding a few different cases, but what can I do to identify the difference?
